Topic: 2 internal NIC's - separated

[Steve]

I am looking for some suggestions on how to achieve the following.  I want to use 3 NIC's.  One for internet access, and two for internal networks.  However, I do not want the internal networks to be able to access each other, for security reasons.  Is there anyway for one e-smith server to do two separate NAT's?

e.g.

(eth0) Internet  24.x.x.x
|
e-smith
|---------------|
(eth1) NAT1 10.0.0.1 & (eth2) NAT2 192.168.0.1


Thanks!
